Designed and implemented REST API backends using Java, Spring Boot, and PostgreSQL with clean architecture and scalable design patterns. Implemented multi-role authentication and access control using Spring Security, JWT, and OAuth2 across enterprise applications. Worked with TypeScript on frontend integration (React), ensuring consistent REST API consumption across web and mobile clients. Migrated 8 legacy MyBatis repositories to Spring Data JPA, created documentation, and maintained handover-ready code. Built CI/CD pipelines using GitHub Actions and Docker, and deployed/managed services on AWS with secure environment configuration.

Developed backend APIs using Java and Spring Boot, contributing to database design and frontend integration within an Agile team. Worked across full-stack delivery for multiple projects including an AI-powered document search platform with metadata indexing and AI-assisted content discovery (evaluating and refining AI outputs), a web field management platform with secure multi-role RBAC and REST APIs backed by PostgreSQL, and employee attendance/workforce mobile app backend REST APIs with cloud synchronization.
